Special Issue Information
Dear Colleagues,
The forging of titanium alloys is a key metals processing step in the aerospace manufacturing sector. Titanium alloys have traditionally been used in airframe and aero-engine applications, such as compressor disks, blades, large landing gear structures and engine pylons due to their high strength to weight ratio, corrosion resistance and excellent fatigue performance. The majority of titanium alloy components are produced from ingot followed by a multi-stage forging and machining route. As titanium is an allotropic material, it is very sensitive to the effects of forging temperature and strain history with respect to the beta transus temperature. Understanding and predicting the (1) beta to alpha phase transformation, (2) crystallographic texture evolution and (3) phase volume fraction and morphology during forging, for a range of titanium alloys is academically challenging. However, with increasing aircraft numbers and industry requirement to further improve the processing and service life of safety critical titanium alloy components, it is a strategically important metals research topic. The aim of this Special Issue is to capture the current status and use of simulation and characterisation approaches towards predicting microstructural evolution during the forging of titanium alloys.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
